What kind of horsepower are you guys running out west on your CO2 racks?
From my understandings in Ontario, TSSA didn't like trans critical racks being more then 100hp (pretty sure it was 100) which caused some design changes.

TSSA don't like any rack over 100hp without having a power engineer on site full time.
Difficult with these set ups as the MT side and the LT side are piped together unlike a cascade where you can get away with it.(i wanna have a look at one now and see what the power of all motors are??)

I will see one with in the year. Looking forward to it. I have heard some horror stories, but I think the stories were dramatized only because it's CO'2. What start up isn't a crazy few weeks. Then add this new thing.

Shane, Will that one be in the Dallas area? or are you travelin for this? Is it TC or SC-Cascade?

Hey there, I wrote the original story on the CO2 supermarkets in the US and Canada for R744.com and would love to hear more from you guys about your experiences with CO2 for another R744 article about CO2 refrigeration in North America. Do you have an case studies, pics, technical info about your installations you could send me?

probably have to make one, Carnot, the former CSC group and advansor have all done Ice rinks with CO2, not sure of your tonnage you are thinking about but Chillers are out there, mainly custom jobs though, not sure of your ambient temps in the summer but TC co2 is not that efficient right now when you go past the critical point, and really under that it's still just the same old refrigeration just fancier controls and smaller pipes!
